Not sure exactly what you're looking for, but a cursory search on the carrageenan nasal spray found this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8493111/

Not sure exactly what you're looking for, but a cursory search on the carrageenan nasal spray found this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8493111/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8493111/ If I'm not mistaken, Betadine had a version that used something else with the carrageenan, but it was removed from the US market and I don't remember the ingredients. As for my version, the HN environment is a bit too vicious to discuss my personal health methods. I've not been in the mood for phatic intellectual combat for a while now.
